Hi Everyone!!!!
I am using a in-house rendering library. In my recent work, I needed to render split screen for four players ie four cameras for each player.
When I set the render target area of window using SetViewport call, it is being set to valid areas ie for each camera. For example if window size is 1980 x 1024 than for first cam, x, y, width and height params are 0 , 0, 1980/4, 1024, for second cam these values are 1980/4, 0, 1980/4 + 1980/4, 1024 so on so forth. I also verified that viewport is not being reset in-between.

But still I get the result from last cam rendering covering to whole window.
Can anyone help me what could possibly be wrong here?

Thanks!!
Happy coding..
